CORPORATION OF OHIO.

To all whom it may concern:

Be it known that I, GEORGE A. EYNON, a citizen of the United States, and a resident of Cleveland, county of Ouyahoga, andState of Ohio, have invented a new and useful Improvement in Carburetors, of which the fol lowing is a specification, the princlple of the invention being herein explained and the best mode in whichI have contemplated applying that principle, so as to distinguish it from other inventions.

The subject of the present invention is improved apparatus for volatilizing liquids.

One particular use to which the invention will be applied is in the volatilization of liquid fuels for internal combustion engines, and the apparatus is adapted to so perfectly intermix the liquid with air that it 15 possible to volatilize exceedingly heavy fuels such as kerosene, and even heavier liquids. of such apparatus will be readily seen in view of the attempts which are bein made to find means forutilizing the heavier distillates of petroleum for the purpose of operating internal combustion engines. By thus referring to the use of the present invention in connection w1th 1nternal combustion engines, to limit the same to this use, as many other adaptati0ns of the invention will'readily suggest themselves to men skilled in the various arts.

To the accomplishment of the foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims.

The annexed drawing and the following description set forth in detail certain means illustrating the invention, such disclosed. means illustrating, however, but one of various ways in WhlCh the principle of the invention may be used.

In said annexed draw1ng:F1gure 1 1s a central vertical section (partially in elevation) illustrating my invention; Fig. 2 is a section of the same on the line 22', Fig. 1; and Fig. 3 is a perspective view of a detail of construction.

most entirely for the purpose of volatilizing the lighter distillates,

such as gasolene. The present trend of development in this industry indicates that in the near future some means will be required which will operate as efficiently to volatilize kerosene as the present carburetor does gasolene. The greater specific gravity of the kerosene makes the present problem much more difficult than that met with in volatilizing gasolene, and a much better intermixture of the air and fuel is necessary to give equally good and better results. Itis to secure'this com- "plete and perfect intermixture of the fuel shown comprises a carbureter of the floatless type provided with a liquid fuel chamber leading to a mixing chamber 51. The latter is tubular in form being supplied with air through an opening 52 in a lateral extension 53. The conduit 54 which leads from the chamber 50 passes through chamber 51 and is supported on the bottom of the same by a tube 55, threaded to receive valve 57 at its upper end. Such valve 57 controls the discharge outlet 58 from the conduit 54, the valve being properly adjusted by a lmurled nut 59 on the rod 56. The outlet 58 also receives a second valve 60 extending through a cylindrical casing or carbureting chamber 61 attached to the outlet part of the conduit 54. This casing 61 is enough smaller than the mixing chamber proper to permit of'some air passing up around it. Such air has two means of outlet, one around a disk 62 resting upon the casing 61, and loosely fitting in the chamber '51 and the other through apertures 63 in rod 56 attached to a needle is integral with valve 60 and is maintained normally in the pos'tion shown by a spring 64 operating against a collar or cap 65 supported in the casing.

The action of'the carbureting chamber is as follows: The casing 61'is provided with a plurality f spaced apertures fifi in its bottom through of the casing, these latter corresponding in number and position to those in the bottom. I

The liquid passes from the valve 57 laterally and is caught up andcarbureted by the air currents forming a number of separate columns of mixed vapor and air. Each column is given a certain internal movement by the size and position of the upper aperture passes thus prelinnn'arily,

through which it mixing the carburetant and air. Upon passing through the a ertures 67 and the apertures 63 in. the dis "-is such that the valve only opens upon a 'cessfully applied to the volitilization of gines,

. The new and very considerable increase in the vacuum in the chamber 51, it opening only after the disk 62 has been raised.

.The usual type of throttle control is provided, a butterfly valve 76 being pivoted in the mixing chamber. Below the same is an inlet 7 7 controlled by a valve 7 8 which may be connected to asourcc of fuel such asgasolene for starting purposes.

The foregoing apparatus has been found, from actual tests, to secure an extremely uick atomization, even of relatively heavy liquids, anda practically perfect mixture of the vapor with the air. The various uses to which such apparatus can be applied need ingthere be enumera edns they will readily suggest themselves to those skilled in thevarious arts. It in ty be mentioned, however, that the invention has already been suckerosene' for use n. internal combustion engoing description has dealt with such an application of the invention as affording the best and clearest illustration of the preferred forms of the apparatus.
